Redditor Txmaluda works at a Whataburger and used their little ketchup-tubs to construct an AT-AT Walker during a slow shift. Bravo!
Update: From the comments, robcruickshank sez, "I hope the rebels mustard a defense." I hope so, too, Rob.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
